Designing for Manufacturability in Riveted Joints
The study of human experts in the areas of design and manufacturing has lead to two hypotheses concerning the problem solving methods which these engineers utilize to attack difficult problems. The basis of both hypotheses is a modular approach to problem solving. One hypothesis addresses the nature of the modules utilized while the other hypothesis deals with the organization of the modules. A...
متن کاملFatigue strength evaluation of self-piercing riveted cold rolled steel joints under mixed mode loading conditions
Fatigue strength of cross-shaped specimens of SPR joints made of SPCC was evaluated at load angles of 0°, 45°, and 90°. For the static strength at load angles of 0°, 45°, and 90°, the maximum loads were determined to be 4890N, 1969N, and 1611N, respectively. Regarding for the relationship between the load amplitude and the number of cycles (Nf), the results were 014 . 0 3 . 2209 − = f amp N P ,...
متن کاملA Practical Engineering Approach to Predicting Fatigue Crack Growth in Riveted Lap Joints
An extensive experimental database has been assembled from very detailed teardown examinations of fatigue cracks found in rivet holes of fuselage structural components. Based on this experimental database, a comprehensive analysis methodology was developed to predict the onset of widespread fatigue damage in lap joints of fuselage structure. Several computer codes were developed with specialize...
متن کاملOptimal Riveted Joints Design of Frame Strcture by IGA
Department of Systems and Information Engineering, Ashikaga Institute of Technology, Ashikaga 326-8558, Japan † Fuzzy Logic Systems Institute, Iizuka 820-0067, Japan Abstract In this paper, we formulate an optimal riveted joints design (ORD) problem of a through gusset plate on a frame structure for a constrained allowable stress as a rigid structural calculation problem and solve it directly b...
متن کاملResidual Strength Analyses of Riveted Lap-Splice Joints
Aging aircraft may develop multiple-site damage (MSD) that can reduce the structural integrity of fuselage structures. The existence of small cracks emanating from adjacent rivet holes in a fuselage lap-splice joint is of major concern. Small collinear cracks greatly reduce the residual strength of a panel with a lead crack. Recent studies predicting the residual strength of flat and curvilinea...
